On the 10th of the mission of the Tianzhou V cargo spaceship, the whole area joint training between the systems before launch was organized. At present, the systems of Tianzhou V cargo spaceship have been ready for launch. This mission is the end of the year 2022 of Wenchang Space Launch Site and the 200th space launch mission of Xichang Satellite Launch Center. In view of the fact that this mission is highly parallel with the Mengtian experimental module mission, deeply coupled, and the launch interval is short, the scientific and technological personnel have fought under pressure, continuously fought, and persevered. They have organized and completed the test and refueling of the technical area of the Tianzhou 5 cargo spaceship, the vertical final assembly test of the Long March 7 carrier rocket, the joint test of ship and rocket, and the vertical transfer of the assembly, and carried out the functional test and data interpretation and comparison in strict accordance with the standards, At present, all systems are in good condition, and preparations for rocket injection are being carried out as planned. "This is a comprehensive simulation exercise with the largest number of test systems besides ignition launch, and it is also the last joint exercise before launch." Zhong Wen'an, Chief Engineer of Xichang Satellite Launch Center, "According to the climatic characteristics of continuous rain during this mission, Long March 7 rocket itself has relevant technical design for waterproof and moisture-proof. At the same time, the launch site has also carried out waterproof and moisture-proof treatment for the ship and rocket assembly before vertical transfer. At present, the equipment and facilities are in good condition, and the weather during the launch meets the requirements. We are confident and determined to complete the launch mission and ensure that the mission of" express delivery "of Tianzhou will be achieved." (Liu Xinshe)
